INVESTIGATION OF THE SELENIUM STATUS AND ACTIVITY OF THE ANTIOXIDANT SYSTEM IN THE ROMANOV SHEEP IN THE NORTH-WESTERN REGION

The extension of the characteristics of the cattle ration is widely spread nowadays. One of the most significant nutritional element is selenium. Selenium has antioxidant function because it is a necessary part of the antioxidant enzyme glutathione peroxidase. There is a deficiency of selenium on the large territories of Russian Federation, especially on North-Western region. The selenium deficiency is the reason of different metabolic diseases and stiff lamb disease. All of the aforesaid leads to production loss. In this article it is firstly reported about selenium status, biochemistry characteristics and their variations after treatment selenium –containing drug among Romanov sheep in north-western region. In the course of study was found that selenium concertation in sheep serum was lower than normal. The selenium drug administration was led to an increase of serum selenium concertation

Study of Rhizobia Impact on Nutritional Element Concentration in Legumes

The concentration of nitrogen in the Earth’s atmosphere is about 78%, but most plants are not able to acquire it directly from the atmosphere. One of the most common ways for binding atmospheric nitrogen is the development of an efficient symbiotic system between legumes and rhizobia. The aim of this study was to compare how different legumes and rhizobia symbiosis systems affect the concentrations of nutrients and other elements in soya and faba beans. Seeds of plants were inoculated with a preparation of rhizobia just before sowing. Plant samples were collected at the flowering stage (vegetative parts) and during harvest (seeds). Samples were air-dried and analysed with inductively coupled plasma mass spectrometry (ICP-MS). Total nitrogen and carbon concentrations were determined with an elemental analyser (EA). The obtained results showed that inoculation of legume plants with rhizobia not only affected nitrogen uptake by plants but also uptake of other elements. Inoculation had an effect on mineral element uptake for both faba bean and soybean leaves, where a significant increase in Mg, P, K, and Ca was observed. Treatment of legume plants with rhizobia caused a decrease of P and K concentrations in seeds, and there were changes in Fe and Mn concentrations.

The halo effect of biofortification claims on taste inference and purchase intention

PurposeThe purpose of this research is to investigate how biofortification claims impact consumer food taste inference and purchase intention. Based on the halo effect, the authors propose that food products with biofortification claims are inferred to taste better than regular foods. Due to this inference, biofortification claims subsequently improve purchase intention.Design/methodology/approachTo examine these predictions, the authors conducted three between-subject design lab experiments featuring three staple foods: corn soup (β-carotene biofortification claim present or not), cooked rice (zinc biofortification claim present or not) and uncooked rice (zinc biofortification claim present or not). Participants were randomly assigned to one of two bioproduction claim conditions (present vs absent). Then, taste inference, purchase intention, consumer characteristics and confounding variables were measured.FindingsIn Experiment 1, the results showed that biofortification claims indeed appeared to evoke a heuristic halo effect, in which foods with biofortification claims were inferred to taste better than regular food. In Experiment 2, the results showed that participants had more intention to purchase foods with biofortification claims than regular food. The mediation effect of taste inference between biofortification claims and purchase intention was examined. In Experiment 3, the data further showed that this halo effect was more pronounced when consumers held a higher preference (vs lower preference) for the enriched nutritional element.Originality/valueBiofortification claims have commonly been viewed solely as information about nutrition value for consumers. However, little is known about how biofortification claims impact hedonic consumer expectations. In this paper, the authors find that biofortification claims alone can impact consumer food taste inference, as nutritional information is not related to actual food taste. These findings extend the authors’ understanding of the psychological mechanism behind consumer attitudes towards biofortification.

Contemporary problems of missionary work among the Samoyedic peoples

The article examines one of the most important traditions of the Samoyedic peoples, which complicates the mission of the Russian Orthodox Church — the consumption of fresh blood of a young deer. This tradition refers to the practice of sacrifice, so it cannot be fully accepted by the Church as there is a canonical prohibition against consuming blood. As a result, a problem arises that hinders a successful mission among the Samoyedic peoples and impedes the growth of the Church. Despite the ban, there is also a modern medical assessment on the use of animal blood by humans, according to which a certain benefit of blood as a nutritional element is recognized. The state, in turn, is interested in maintaining the traditional way of life of the Nenets. It can be stated that the ban penetrated into new Testament Christianity under the influence of Judeo-Christians. The purpose of this article is to examine the effectiveness of missionary activity among the Samoyed peoples and to identify the possibility of missionary reception in light of the cultural tradition. The authors propose a new strategy for missionary work among the Samoyed people, which will be feasible if the Council of Bishops will consider relaxing the canonical prohibitions for the Samoyeds.

Implementasi Forward Chaining dan Metode Simpleks untuk Menentukan Ransum Unggas yang Ekonomis

Poultry need food to maintain their lives and to produce. To meet the needs of these nutritional elements, poultry eat from various types of food. Because there is no single food ingredient that contains a complete nutritional element, so we need a variety of appropriate and balanced food ingredients to meet nutritional needs. This can be done by choosing cheap food ingredients without ignoring the quality of the nutritional content that is adjusted to the type and age of poultry. To solve the above problems, an expert system with a forward chaining method can be used to determine the nutritional needs and nutritional content of food ingredients, while linear programming with the simplex method is used to determine the combination of poultry feed-forming ingredients that meet economical poultry nutritional needs. The combination of the forward chaining method and the simplex method can accelerate the preparation of combinations of food ingredients, so that the resulting application can provide a solution in making decisions for the selection of food ingredients forming ration effectively

The influence of organo-mineral fertilizers on the formation of productivity of strawberry integrated agrocenosis

In 2012-2016 the research was carried out in order to study the infl uence of fertigation and foliar feeding by liquid organo-mineral and mineral fertilizers in chelated form on productivity of strawberry agrocenosis in unstable weather conditions. On average, it was revealed that over fi ve years of research the increase in biological yield on the variety Elsanta was 26.1 %, 27.1 % and 33.4 % in cases with foliar feedings by Raykat, Aminocat, Megafol. For Vima Xima strawberry variety, the yield increase was 16.9-29.0 %, however signifi cantly higher yield increase was revealed after Aminocat applying — 29 %. The use of liquid organomineral fertilizers containing nutritional element in chelated form in Elsanta variety plantations, on average over 3 years, was showed a signifi cant yield increase (12.5 %), in the variant with Kelik Calcium + Boron application and for Vima Xima strawberry variety in the the variants supplemented by Floron (19.25 %) and by Atlante Plus (11 %). High biological effi ciency was observed during the formation of productivity on organic and mineral fertilizers Raykat, Megafol, Aminocat, Megafol.

Omega-3 Fatty Acids as an Essential Nutritional Element in the High North

This chapter considers specific nutritional factors of indigenous peoples in Russia's Arctic zone. The authors have identified the prerequisites for the optimization of the diets of indigenous peoples in the light of existing environmental and medical-biological problems. A low level of self-sufficiency of local population with basic food products (meat, dairy, and egg products) was identified. The chapter provides a detailed analysis of the chemical composition of chia seeds as a promising ingredient of the northern diet, in particular the biological value of a product based on protein, lipid, carbohydrate, mineral, and vitamin components. The authors proposed considering chia seeds as a part of the composition of various food products for functional purposes. Potentially, the inclusion of scientifically based food recipes in the diets let providing the indigenous people with balanced food products.
